• nanostructured forms, such as nanowires, nanoribbons, nanobelts and as tetrapods [11], and their potential use in NO2 gas sensing in these forms is well known [12][13]. In this study we investigated the effects that two very different types of organic ligands imposed on the sensitivity and response of

• for UV photodetection, to avoid the need to use a gas cavity to load the nanowires, simplifying the device fabrication. Recent experiments have demonstrated that coating ZnO nanobelts with UV-sensitive polymers enhances the UV photoconduction [13][14]. A thin layer (<100 nm) of such a polymer over ZnO

• anatase TiO2 nanobelts, onto which SAMs of long chain carboxylic acids, exposing hydrophobic terminating groups, were chemisorbed [88]. An UV-induced compressive force between the nanoparticles and the TiO2 nanobelts could be inferred based on Raman spectroscopy. To our understanding, this compressive
